Bare metal != On premise
There are plenty of hosting providers that will provide everything you mention plus the actual servers for a monthly fee without requiring you to buy anything.

Trying to be helpful and not pedantic: "On premises" or "on prem" are good choices here, while "premise" means something else (e.g. "The premise of moving off-premises is that we can pay a little more in order not to worry about stuff that isn't our company's primary business.")
Very common, for sure. And although I think it's worth professionals being aware of the difference, I tend not to bother with less technical folks.
> I wonder if 20 years from now the word premise would have a different meaning.
Given that "literally" is now often used to mean "figuratively", it's absolutely possible!
There is no calculus that makes aws cheaper unless you need extreme variability or some of their managed services and even then, you can usually use those services in conjunction with your rented bare metals.
